We have a BetaPI pressure Gauge with a RS232 output and a USB-9219 module to acquire data in one LabVIEW application. The 9219 is set up continuous samples at 5Hz, and the Gauge is set up at 1 sec update time. See the attached file for our starter code.
This system will be developed to test questionable pressure transducers against the calibrated Beta Gauge. Both devices will be supplied with oil and held under pressure at 10 different points, starting from zero. The 9219 will have inputs in various forms of analog data. We want to synchronize the data from both sources and read to one graph continuously and in real time and to send data to a report file once the user commands so. At the moment we are unsure how to get these two readings to synchronize. Writing to graphs and files has been achieved for each device independently, so this should not present much difficulty.
Let us know if more information is required.
Thanks,
Brian
